Comparison of quantification of intraretinal hard exudates between optical coherence tomography en face image versus fundus photography.

ABSTRACT:

Purpose

To compare the quantification of intraretinal hard exudate (HE) using en face optical coherence tomography (OCT) and fundus photography.

Methods

Consecutive en face images and corresponding fundus photographs from 13 eyes of 10 patients with macular edema associated with diabetic retinopathy or Coats' disease were analyzed using the machine-learning-based image analysis tool, "ilastik."

Results

The overall measured HE area was greater with en face images than with fundus photos (en face: 0.49 ± 0.35 mm2 vs. fundus photo: 0.34 ± 0.34 mm2, P < 0.001). However, there was an excellent correlation between the two measurements (intraclass correlation coefficient [ICC] = 0.844). There was a negative correlation between HE area and central macular thickness (CMT) (r =
